c# - How 2 WebAPI Routing can accept same type parameter -

i have web api has several methods. have problem routing. have 1 method returning products yearid , method returning product product id. here 2 routes came with:

   /api/records/products?yearid=10     /api/records/products/15 

these 2 methods:

    [httpget]     [route("getbyyearid")]     public async task<product> getbyyearid(int yearid)     {           .....          }       [httpget]     [route("getbyid")]     public async task<ienumerable<product>> getbyid(int productid)     {         ......     } 

what route mapping should have can access web api these 2 routes:

    /api/records/products?yearid=10      /api/records/products/15 

you using attribute routing customize how want routes used.

here example of how can achieve routes wanted:

[routeprefix("api/records")] public class recordscontroller: apicontroller {     // api/records/products?yearid=10         [httpget]     [route("products")]     public async task<product> getbyyearid(int yearid) {           .....          }      // api/records/products/15     [httpget]     [route("products/{productid:int}")]     public async task<ienumerable<product>> getbyid(int productid) {         ......     } }
